I&#39;m working with a SP list that needs to have validation to ensure if a certain value is selected for item type, the title must NOT be unique. This is being used to link together Parent and Child items in my list.</p> <p>Column A - Title (multiple lines of text)</p> <p>Column B - Item type (choice: n/a, Parent, Child)</p> <p>I&#39;m trying to enforce that if Column B is set to &quot;Child&quot; then Column A must match an existing Title in the Sharepoint list.</p> <p>I would appreciate any direction you can give me in solving this issue.</p> <div style="clear:both;"></div><img src="http://msmvps.com/aggbug.aspx?PostID=1809839" width="1" height="1">http://msmvps.com/blogs/shareblog/archive/2012/02/28/conditional-requiring-of-fields-using-sharepoint-2010-list-validation.aspx#1807042Tue, 06 Mar 2012 23:17:04 GMTd67277c4-116b-43f1-b688-e9ef184ea916:1807042Priyanka<p>Gary,</p> <p>Awesome!!
